If the Oklahoma primary tells us anything, its that conservaDem DINOs who vote for Repubilcans in the general were more likely to support Sanders than Clinton. The Obama-Clinton connection that she's made has cracked her white conservative Democrat support.
Or one can argue that the conservative Democrats/Dixiecrats/DINOs have crossed over and are voting in the Republican primaries, which I think seems more plausible, especially in Oklahoma as Republicans continue to make gains among registered voters, and if conventional wisdom holds true that there aren't that many white Democrats left in the South as Democrats become more urban and Republicans become more rural. This is true if you compare and contrast the 2008 Oklahoma Democratic Primary with 2016 and see that Oklahoma County flipped as did every other county with the exception of Osage County (FF county).
